To all whom t mcy concern.'

Be it known that We, WILLIAMW. Moa.

` the following is a specification, reference being had therein to the accompanying drawing. Y

This invention relates ,to corn husking machines and' is a divisionhof the application filed by us Dec. 23, 1909, Ser. No.

' The object of the invention is to provide a single machine of a compact arrangement which will receive an ear of green corn as vit comesl from the. stalk, sever the butt therefrom, remove the husk and silk andi deliver the carin acondi'tion to go to the cutting machine. l A

To this end it is a further object of the invention to provide in combination with a butt-removing mechanism a husking mechanism connected with the butt-removing mechanism by suitable' feeding devices which ivill lconvey the ear of corn to the hashing mechanism and present the same thereto in a lposition to be. properly acted l upon thereby; to provide the husking mechanism with huslr-loosening devices and means for properly positioning the ear to cause it to ,le engaged by said husk-loosening de vices; to provide means which will e'ectually hold the ear in engagement With the rotate the same 'during th@ bushing operation without bruisingr the grains or ,otherwise injuring the corn; and fr i'rtl'ier, to so improve the construction of thehuslting mechanism as to more effec tually remove the husks from tbe green corn without injuring the corn.

Aembodiment of our invention and have shown the same as comprising ainain frame consisting of side members 1 connected @ne to the other by transverse bolts or bars 2 having mounted thereon spacing sleeves 3, which sleeves are arranged between the side members l. This main frame is supported standards or legs 4 which are secured to the respective sidemembers l. by means of the bolts 2 and are mounted at their lower ends upon supporting blocks or transversely extending bases 5 which serve to tie tof-A g'ether 4the legs of each pair, that is, the two Longiare secured to the legs on vthe respective sides ot. the machine oy means of bolts 7 and serve both to connect togeth ir the legson the same side of the machine and to form a support for'certain parts of the mechanism to be hereinafter described.

Butt-removing mechanism of a suitable character is preferably mounted on the upper portion of the main frame between the' ends thereof. This mechanism, as here shown, comprises a rotary cutter 8 mounted on a shaft 9 extex'idingr transversely tothe main frame and journaled in bearings 10. A suitable supporting table or bed. plate 18 is arrangedv with one edge adjacent to lthe cutter and e ears of corn are fed .over this bed plate to vard the cutter by suitable eeding mechanism which, .in the present construction, compi-lees an endless carrier consisting of two sprocket chains 1Q arranged' on opposite sides of the supporting: table and extending about sprocket Wheels 205 carried by a shaft 21 gournaled in the main frame' near one end of the supporting table and other sprocket Wheels 24 mounted on a shaft l? arranged near the other 'end of the supporting table. .This feeding mechanism may be driven in 'any suitable manner but We have here shown the shaft 21 as having securedthereto a sprocket wheel 25' about which extends a sprocket chain 2 6 which' also .extends about a sprocket Wheell 27 on a stud shaft 28 -to which motion is imparted by means cfa second sprocket Wheel 29 about which'extends a. sprocket chem 3Q 'which also extends' about a sprocket Wheel' 3l on a driving shaft 32 journaled in snit.-A able bearings on the main trame and to which poivernmy be applied in anysuitahle manner, as by mesas ai belt e3- Eait'ehe ver easases er@ seemed te losA meneer connected et tlieir upper ends to the opposite side members of the mum freine' and ere resiliently connected et their. lower ends to tbe' plete 6l, this connection preferubly comprsi'n'ggj,4 iu eecl'i instance, a bolt 66 extending through o lugJ G7 on tbe plete oil and through e corresoondine, lug 68 on tbe pivoted plete 55. A. spring GQ is coiled about tlie bolt 66 und confined bet-Ween the ,111g 68 und u, nut TG. The 'tension oi' the spring tends to bold die outermost roller of eeeli pair in contee-t Vwith tbe innermost roller oi" the corresponding Deir. but .permits the rollers to move spurt sullciently to ellovv the husks to between tbe seme. ln this manner we secure e strong ggriopingl action by the rollers withoutliability of choking' tbe rollers with liuslrs.

The luisking rollers may., of eourse, be of any suitable construction, but, in tbe construction here shown, they are mede up of plurality of sections or cylinders of iron,

covered with rubber. The rst pair of rollers, comprising the individuel rollers 71 and 7:2, are provided with special means for loosening tlie husk on the ear. To this end the sections of iron und rubber of the roller 72 are spaced eport and nove arranged. lietxveen them toothed disks or ster Wheels 38, Wliile sections oi2 tlie roller Il ere divided et points in elineinent with the toothed disks 73 by narrow disks which form grooves 7d adapted to receive the teeth of the disk 73. lt will be apparent that the toothed disks will teur und loosen tbe husk on tbe eer in' such u manner us to enable tbe rubber covered portions of the rollers to more readily grip the' seme. Further, the rollers 7l and 72 are provided et one end with intermesbingtootlied disks 75.,.Wliich disks.

ore adapted to engage the tip of the eur and teer tbe husk loose therefrom. The seveivil,`

sections comprising; euch roller are mounted upon shafts 76 which are journoled lill the plates Gfl and 65 und beve arranged between the the roller collars 'T vehicle .serve to retain 'tbe sections in their positions on tbesbuft und also :torni supports for tlie lugs 53 in which the bearing rollers 5l. of the leed belt are mounted, und thus prevent tbe feed rollers coming in contact' with the teeth or with tbe boeking rollers should the 'feed belt become sleek. The second pair of rollers, 78, are built up merely or sections of rubber covered iron end serve to remove l manner the brushes ore inner foce or" the plete and the ends of' the roller 7l, extends beyond the binier and busl'ioouuted thereon u sprocket Wheel 80, about which extends e sprocket chain lll which also extends aboutie sprocket Wheel S2 on tbc drive shaft 32. This sprocket chain qu; also extends about an'idle sprocket Wheel 83 l adjustebly mounted on the moin fiume und serving'botli es a guide und es e tigbtener for the chain. Suitable devices are arranged' ebove the 3 5 boeking rollers lof ea'ch peir'to' engage thel euro? eol'n and liold the same vlirrnlyjin enf. gagement with tbe` liusking roller und to rotate tbe some while it is in engagement 'with these rollers. These devices pref- @o erebly consist of rotary members, suoli es the rotary brushes Sil, one of which is supn ported above each peil' of buskiu rollers und preferably lios its axis arrangedabetween the vertical planes of the axes of the two g5 ,boeking rollers constituting the pair. ln

order that the roturv members or brushes inuyj accommodate themselves to ears of varying thickness und muy exert a1u1iform pressure on tbe eers they are so mounted o@ as to be capable of n vertical movement. To ziccomplisli this the first brush, in the order in which they are encountered bythe eur, is 'journnled in the ends of e pair of l parallel urine 85 which extend rearwardly 95 from tbe sbait 28, on'whicli they aire p'ivy oto-ly mounted. The second brush 84 is )ourneled in the loi-ward ends'otu second pair of arms 86 which are pivotuly mounted upon the slieit oi the first brush 84:. The we two brushes 8lure conne/ted one to the other by means of e. sprocket chain 87 ex-- tendingebout sprocket Wheels 88 mounted on tbe shafts of the respective brushes. The

lirst brush S-l is Apositively rotated by means me of e sprocket chain 89 extending about a sprocket wheel 90 on one end of the shaft of the brush and about :i second sprocket Wheel Ql mounted on tbe shaft 28. ln this' positively rotated i719 und servefnot only to bold the ears of corn in engegeiiienl with the 'boeking rollers and to rotute the eers of corn but also serve to remove tbe silk from tbe vears of corn after the husks have been removed. The brushes lilo engage tlie ear und remove the silk there:

from simultaneously with the action of the husking rollers7 the brush engaging the silk :is soon as the rollers have pulled thehusk from the enr sufcientlv to expose the silk. tot) As above stated, the husking rollers of' the first pair are provided with two inter 'meshing tootheddisks T5 which assist inY it ls'clesreble toet seme mesme should. be

w1 i shaft 'Q3 .which extends through a longitudinal bearing formed in a bearing bracket 94, which bearing bracket has also a 'transverse bearing, by means of Which it is pirotally supported on the 'shaft 17. That end oi' the shaft 93 which extends beyond the longitudinal bearing ol the bracket 9st has secured thereto a bevel pinion fwhich meshes' with a second bevel pinion 96 seoiiree to the shaft 17. The shaft 93 of the roller extends through the slotted lower end oi the'braoltet 9'4" which serves to limit the downward movement ol' the roller, but permits the .roller to rise and fall and thus ao commodate itself to the various sizesoof ears. 'The two rollers may be arranged in any del position, butl We prefer to arrange them nea; the opposite side members of the main Suitable means are also provided 'for rcymovingthe silk and bits of husk from the bushing rollers and maintaining the same tree from obstructions of this character.

' 'ihismeans preferably comprises a pluralityv of rotary brushes 98 which have their shafts iounaled in kbrackets 99 which are mounted on the bearing plates in which are journaled the shafts or the bushing rollers. These 'brbshes are rotated, by means of a sprocket chain 10.0 extending about sprocket wheels lOl secured to the ends of the shafts oi the respective brushes and also extending about an idle sprocket wheel `102 adjustably mounted on the main frame and a sprocket wheel 103 secured. to the shafft ofthe outer l bushing roller of the last pair.

' The' endless feed belt which has conveyed the ears oi corn through the butt-removing mechanism, through thechute and across the hnsking rollers, discharges `the same into a chute 104, which, in turn, delivers the husked l ear into a receptacle or onto a suitable oonbelt conyeyer 105 Whieh'eXtend-s about drums Voyer, as may be desired. flhe hasks drop from 'the bushing rollers onto an endless or rollers 108 having their shafts journaled in brackets 10'? which are 'adjustably mount` ed onthe longitudinal side members 6. @ne

of these shafts, that neartheforward end of themacliine. has a sprocket Wheel 108 about which extends the sproclte'tchain 26 which ertends about the sprooket-Wheel 25 of the 'El and the sprocket Wheel Q7 of 'The 'botte which are severed d i idonea? vby the rotary cutter drop into a chute 109 and are 'also delivered to the conveyer 105 which extends beyond "he main :frame at one end.

The operation of the machine as a Whole )vill be readily understood from the foregoing description oi the several parts ther-eel and it will be apparent that the construction and arrangement of the several parts is such that the ear of corn is first presented to the batting vmeclnxnisni and after it has been acted upon by this batting' mechanism is fed to the husk removing devices and-is positively inoved into a position to be properly acted upon by the husk-ing rollers and by the husk loosening devices copemting` with said rollers;` that the ear will. be held Iin engagement with the bushing rollers and rotated during the bushing operation 'Without bruising` the grains of corn or injuring the ear; that the basking rollers will maint a strong gripping action on the huslts but will vinlove apart to permit the passage the, husks, thus avoiding the choking of the rollers with the huslrs; and that the rollers and the husk-loosening devices will be freed from any liusks or silks which may adhere thereto. It will furtherbe apparent that the machine as a Whole is of a Very compact al."- rangement and is simple in its construction and operation.

lt will further be noted that the removal otl the butt of the ear serves to loosen the huslts thereon and thus facilitate the action -o the husking mechanism When'the ear has been fed to the latter.

While We have here shown one forni of our invention'we Wish it to be understood that this form is chosen for the purpose oi' illustration onlyand we do not desireto bc limited to the details'of construction shown and dtlscribed, for obvious modications will occur to a person skilled in the art. A
